Journal Article
Allende Prieto, C., Aguado, D. S., González Hernández, J. I., Rebolo, R., Najita, J., Manser, C. J., …Zou, H. (2023). GTC Follow-up Observations of Very Metal-poor Star Candidates from DESI. Astrophysical Journal, 957(2), Article 76. https://doi.org/10.3847/1538-4357/acfa96

The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of ∼10, improving the sample statistics to study the early chemical evolution of the Milky W...

KURVS: the outer rotation curve shapes and dark matter fractions of z ∼ 1.5 star-forming galaxies (2023)
Journal Article
Puglisi, A., Dudzevičiūtė, U., Swinbank, M., Gillman, S., Tiley, A. L., Bower, R. G., …Sharples, R. M. (2023). KURVS: the outer rotation curve shapes and dark matter fractions of z ∼ 1.5 star-forming galaxies. Monthly Notices of the Royal Astronomical Society, 524(2), 2814-2835. https://doi.org/10.1093/mnras/stad1966

We present first results from the KMOS Ultra-deep Rotation Velocity Survey (KURVS), aimed at studying the outer rotation curves shape and dark matter content of 22 star-forming galaxies at z ∼1.5. These galaxies represent ’typical’ star-forming discs... Read More about KURVS: the outer rotation curve shapes and dark matter fractions of z ∼ 1.5 star-forming galaxies.

We describe the Milky Way Survey (MWS) that will be undertaken with the Dark Energy Spectroscopic Instrument (DESI) on the Mayall 4 m telescope at the Kitt Peak National Observatory. Over the next 5 yr DESI MWS will observe approximately seven millio... Read More about Overview of the DESI Milky Way Survey.

Characterisation of detachment in the MAST-U Super-X divertor using multi-wavelength imaging of 2D atomic and molecular emission processes (2023)
Journal Article
Wijkamp, T., Allcock, J., Feng, X., Kool, B., Lipschultz, B., Verhaegh, K., …Jaspers, R. (2023). Characterisation of detachment in the MAST-U Super-X divertor using multi-wavelength imaging of 2D atomic and molecular emission processes. Nuclear Fusion, 63(5), Article 056003. https://doi.org/10.1088/1741-4326/acc191

In this work, we provide the first 2D spatially resolved description of radiative detachment in MAST-U Super-X L-mode divertor plasmas. The Super-X magnetic configuration was designed to achieve reduced heat- and particle loads at the divertor target...

DESI Observations of the Andromeda Galaxy: Revealing the Immigration History of our Nearest Neighbor (2023)
Journal Article
Dey, A., Najita, J. R., Koposov, S., Josephy-Zack, J., Maxemin, G., Bell, E. F., …Zou, H. (2023). DESI Observations of the Andromeda Galaxy: Revealing the Immigration History of our Nearest Neighbor. Astrophysical Journal, 944(1), Article 1. https://doi.org/10.3847/1538-4357/aca5f8

We present DESI observations of the inner halo of M31, which reveal the kinematics of a recent merger - a galactic immigration event - in exquisite detail. Of the 11,416 sources studied in 3.75 hours of on-sky exposure time, 7,438 are M31 sources wit...

Wavelength calibration of birefringent interferometers for 2-D measurement of plasma flow (2023)
Journal Article
Allcock, J. S., Silburn, S. A., Sharples, R. M., Harrison, J. R., Conway, N. J., Long, T., & Lin, N. (2023). Wavelength calibration of birefringent interferometers for 2-D measurement of plasma flow. Optics Express, 31(2), 1901-1915. https://doi.org/10.1364/oe.473278

Imaging birefringent interferometers are used to measure plasma flow in 2-D via the Doppler shift of a spectral emission line. Applications include plasma physics study in fusion energy experiments and in the Earth’s upper atmosphere. We present a ne...
